It's like Google with his Android apps on his chromebooks?
Interesting. I use an iBook and iPhone extensively. I find the iBook useful for certain things, but I hate it for running applications that I need to get work done with. Curious to see what they come up with.
If you install the Mojave beta on your macOS system, you can test 4 of Apple's apps that have been ported from iOS and will be part of the next Mojave release.I assume you mean "iPad"?
It does sound interesting, but I'm unlikely to try. I still have El Capitan installed, I'm conservative in upgrading. It always seems that upgrades end up as time sinks.
